(CNN)–Cindy McCain is giving a long, personal speech - as did Michelle Obama. And she's doing a fine job, as did Michelle.
I don't think even Hillary Clinton gave such a long and substantial speech on behalf of her husband in 1992. We have entered a new era in politics, and Michelle and Cindy are a big part of it.
I will note that Democrats have not attacked Cindy the way Republicans have attacked Michelle. Even mild-mannered Mitt Romney bitterly and unfairly attacked Michelle last night.
Attacking the wife is clearly a Republican thing - recall how Bush supporters smeared Cindy McCain during the 2000 South Carolina primary, then how they bitterly attacked Teresa Heinz Kerry in 2004. It's a classic double standard and a typical Republican philosophy: do as I say, not as I do.
